my power steering belt keeps falling off at high rpms idk whats causeing it to happen and also when i shift into second (without the belt on) the car jerks almost like the engine is shaeking alot? but i checked all the motor mounts, ]how many mounts are there?

 

its either a worn belt or a bad tensioner

 

what could be makeing the engine jerk? loose mount or somthing?

 

it maybe be that the motor is unbalanced with the belt comming off. I forget how the balncer works in that car. I dont really see that this is the problem but its possible. Or you have a bad motor mount somewhere.

 

we had that happen to a car and it was the bushing that needed to be replaced.

 

the power steering belt seems to come off quite often on the 420a motor eclipses (rs, gs) from my expierence anyways usually around 6500 and up, shift sooner.
